IPmux-16Installation and Operation Manual	Chapter 3 Operation

Note When “unframed” mode is selected, the Idle Code, Signaling Mode, Cond Data Pattern and Cond CAS Pattern fields are not present.

When CAS Disabled is selected, the Cond CAS Pattern field is not present.

➤To change the source of the transmit clock:

• Type 1 and press the <Spacebar> on your keyboard to toggle between

Adaptive/Loopback/Internal/External.

Adaptive:	Adaptive clock regeneration
Loopback:	The E1 recovered receive clock is used as the transmit clock.
Internal:	A local clock source is used.

Default value: Adaptive

➤To change the Loopback State setting:

Refer to Chapter 4 for detailed instructions on loopback tests.

➤To change the RX Sensitivity setting:

•Type 3 and press the <Spacebar> on your keyboard to toggle between –10 dB / –32 dB. This setting determines the maximum attenuation of the receive signal that can be compensated for by the interface receive path.

Default value: E1: -10 dB

➤To change the Line Type setting:

•Type 4 and press the <Spacebar> on your keyboard to toggle between CRC4 Enable / CRC4 Disable / UNFRAMED. This setting determines the framing mode and operation mode for each configuration.

−Unframed: Framer will be configured to pass through mode and the operation mode will be set to Unframed (see Chapter 1, section 1.3).

−CRC4 Enable: Framer will be configured to CRC4 MF mode. Operation mode will be set by Signaling Mode field #6 to either Fractional or Fractional with CAS (see Chapter 1, section 1.3).

−CRC4 Disable: CRC4 MF mode is disabled. Operation mode will be set by Signaling Mode field #6 to either Fractional or Fractional with CAS (see Chapter 1, section 1.3).

Default value: CRC4 enabled

Note Changing the Line Type setting will delete all connections.

➤To determine the idle code inserted into unused time slots by IPmux-16-E1 at the transmit path towards E1 equipment:

•Type 5 (Idle code) and enter a new value.

(This field will not appear if “unframed” is selected in the Line Type field.) Range: 00-FF

Default value: 7E
